Hello everyone,
I have a simple question for you:
In My project I have a button that change ON / OFF realy, so my button control a digital pin that link my relay. After, I add a timer to do the same…now why should I use virtual pin to use timer? By widget button I don’t use skecth and virtual pin, I use only digital pin and works, why isn’t the same? In my project I use button to turn on and off a light (I don’t use sketch and virtual pin, blynk provide to work all). If I use also a timer why doesn’t work? Thank you
Andrea

I think you need to effectively start again with this tread.
Start by providing the basic info about what hardware and Blynk library version you are using, along with a summary of exactly what it is that you’re trying to achieve and why this inst working.
Share the code that you’re using - correctly formatted with triple backticks at the beginning and end.
Triple backticks look like this:
```

Also share details of what you have set-up in your app - what widgets you have, what pins they are connected to, and what their purpose is.

My project works to control the energy of my solar panel.
I use NodeMcu, current sensor INA219 and relay 4ch.
My 2 button set on D5 and D6 simply.
Before timer, I use normally, start and stop without problem.
Actually with 2 timer, only works only start!
Do you need other?
Thank you
SORRY…

One timer widget *(called Faro or Faretto, depending on which screenshot we are looking at) that is connected to pin D4
You have another timer widget (called Madonna) connected to an unknown pin

You have a switch widget (called Faretto) connected to D5 or D6

You have a switch widget (called Madonna) connected to D5 or D6

Can you please clarify the missing information for these widget pins, and explain how the timer on/off switch widgets are able to override the timers when they are connected to different digital pins to the timer widgets?

It’s been painfully difficult extracting the correct information from you about the setup of 4 simple widgets!
If these widgets are configured in the way that you’ve said 8n your latest post (which conflicts with what you said earlier) then they should probably work correctly - but, as I don’t use digital pins, or the timer widget, my personal experience in this area is limited.

However, as I said earlier, virtual pins are much more appropriate for this type of application and that’s the way that I’d go if I were you.

I’d say that any time you have multiple widgets trying to control the same pins then you’re asking for problems.
You may also have multiple things trying to control the same pins, because you’re using mixed referencing for the pin numbers, and it’s also not clear how your current sensor is wired.
